Universal fitment for standard oil filters across various vehicle platforms.

High-performance engines generate significant radiant heat that often soaks into oil filters located near exhaust manifolds or engine blocks. The DEI Oil Filter Heat Shield (MPN 10740) effectively blocks this radiant heat, preventing oil viscosity changes and thermal breakdown that causes oil additives to degrade or dissipate prematurely. Maintaining stable oil temperatures is critical for protecting internal engine components during high-load or track driving.

• Dimensions: 3.5in x 4.5in x 4in (Universal trim-to-fit size)
• Material: Radiant heat barrier with a heavy-duty adhesive backing
• Installation: Peel-and-stick application; easily trimmed to fit various filter heights
• Quantity: Pack of 3 shields
• Use Type: One-time use per filter

By insulating the filter, this kit reduces heat soak and helps maintain lower oil temperatures. The universal design ensures compatibility with most spin-on oil filters, provided the shield is trimmed to the appropriate size for the specific application.
